Abstract:
OBJECTIVE:To investigate the effects of triptolide(TP)on the proliferation of fibroblast-like synoviocytes(FLS) from patients with rheumatoid arthritis(RA)in vitro. METHODS:5 RA patients received knee arthroplasty or synovectomy to ob-tain synovial tissue. FLS was isolated,cultured and identified,and then incubated in the presence of TP [0 (blank control),50, 100 and 200 nmol/ml] for 24,48 and 72 h. The effects of TP on FLS was evaluated by MTT,and then proliferation inhibitory rate was calculated;flow cytometry was used to detect the apoptosis and cell cycle of FLS. RESULTS:The inhibitory rates of TP(50, 100 and 200 nmol/ml)on the proliferation of FLS were 17.46%-52.56%,which was positively correlated with drug concentration. Compared with blank control group,100 and 200 nmol/ml TP could increase the percentage of cells in G0/G1 phase and decrease the percentage of cells in S phase,with statistical significance(P<0.05);200 nmol/ml TP could induce cell apoptosis. CONCLU-SIONS:TP could inhibit the proliferation and also could induce the apoptosis of FLS in RA patients in vitro,which may be one of its mechanism for treating RA.
